(1) Copper is the best material in wristwatches. It is cheap and easy to process. It is mainly used in movements, and most movements use brass alloy plates. The colors of the movements we usually see are yellow and white. Yellow movements are typically coated with titanium oxide, while white movements are made of zinc-nickel alloy.

(2) Stainless steel, a combination of steel, chromium and nickel, is difficult to process. However, it has better corrosion resistance and wear resistance than the former. Its surface can be electroplated or not, and only needs to be polished, sandblasted or sandblasted to create different three-dimensional appearance effects.

(3) Titanium metal has gradually come to the fore, driven by the craze for all-steel watches. Its material is known as "aviation Age" metal. What is titanium metal? Titanium is found in the Earth's crust. Its appearance can be a bright and lustrous metal or a silver-gray or dark gray powder. Titanium is a lightweight, hard, heat-resistant and cold-resistant metal. It has an oxide film on its surface, which can prevent wear and rust.

(4) Tungsten-titanium alloy is first pressed into the blank with tungsten carbide and titanium carbide powder at a pressure of 1000 pascals, then die-cast in a mold, and then sintered in a specially designed furnace at a high temperature of 1450 degrees Celsius to form a component with extremely high density. Finally, after multiple processes and polishing with diamond powder, a shiny tungsten-titanium alloy with excellent wear resistance is made.

(5) Tungsten steel has high hardness, is wear-resistant, has distinct lines on the surface, and is smooth and bright. It is called a "wear-resistant material". It can be used in combination with steel to make watch case bezels or watch straps and grains, enhancing the wear resistance and decorative effect of the surface of the case and strap. (Adding to the court statement, tungsten steel has a drawback, which is that it is too heavy. (6) Precision ceramics: Precision ceramics are smooth, wear-resistant and do not harm the skin. Their main component is zirconia. Under certain temperature conditions, they achieve excellent processing performance. Then, through advanced processing methods, they can be made into exquisite watch cases and straps. They can also be processed in various colors through special methods, making them even more magnificent and noble. (7) High-tech ceramics: Extremely fine zirconia or titanium carbide powder is injected into molds at high pressure and then sintered in a furnace at 1450 degrees Celsius to form wear-resistant ceramic components. Only after being polished with diamond powder can high-tech ceramics with unique luster be made. (8) High-tech lanthanum is made by crushing the rare rare earth element lanthanum and refining it into fine particles. The crude blanks are then compressed in a furnace under high temperature and high pressure. Its hardness is higher than that of tungsten-titanium alloy and high-tech ceramics, it is less prone to wear and tear, and it emits a mysterious glow. (9) Blue steel Blue steel is a type of steel formed through a special smelting process, which is why it emits a deep blue halo color. Blue steel is mainly used for Pointers. In addition to being aesthetically pleasing, it also has corrosion resistance.
